Narrative:

While en route to efd, WX conditions went below landing minimums. Upon arrival at efd captain elected to return to iah. Iah was not a legal alternate (vct on release). The captain notified iah operations of his decision. Operations notified dispatch. Dispatch relayed to operations for captain to hold but captain already was on his return to iah. By the time dispatch was able to contact the flight the aircraft was on 6 mi final into iah. Upon arrival into iah, the captain did go into operations and contact dispatch. He said that while at efd he was unable to contact dispatch, so relayed information to operations. I told him the reason we wanted him to hold at efd was so we could redispatch him to iah with another alternate, making the return to iah legal. During the conversation with the captain it became apparent that the crew was not sure of operation of the communication equipment aboard the aircraft. With proper training on this equipment, this situation could have been avoided.
